AppRedeem is hoping iOS devs will follow Groupon's lead and adopt its UDID alternative.

Just six months after announcing that developers must stop accessing a device’s unique device identifier (UDID) within their iOS apps, Apple put its rule into practice last week amid increasing privacy concerns surrounding mobile apps. Any app submitted for App Store approval will soon be rejected if its attempts to access a UDID, and developers need an alternative.

That alternative could come from AppRedeem, a mobile advertising platform for app discovery, branding and monetization, which has developed a system called Organizational Specific Device Identifier, or “ODID,” already being used by Groupon.
